TECHNICAL FIELD

The present invention relates to a padded seat which is used as beingmounted on a chair.

BACKGROUND ART

Conventionally, among chairs used as office furniture, elbow rests wereoriginally furnished, and the elbow rest was generally installed by wayof a support member raised from the seat side.

Accordingly, in the chairs of this type, a large space was formedbetween the elbow rest and the seat side of the chair, and aircommunicates through this space, and to prevent cooling of the body, ordisclosure of the clothes of the occupant, it was necessary to payattention to the state of the clothes.

In addition, in the case of a chair provided with elbow rests, ifattempted to store the chair in the space beneath the desk, the elbowrests were often obstacles for storing inside.

On the other hand, in the case of a chair not provided with elbow rests,there was no problem when storing the chair in the space beneath thedesk as mentioned above, but there was nothing to shut off the passageof air, and the body was cooled and the clothes of the occupant weredisclosed, and it was necessary to pay attention to the state of theclothes.

In this background, the present applicant previously proposed, in achair generally used as an office furniture, a padded seat having elbowparts capable of solving problems of anticipation to pay attention tothe state of the clothes, due to cooling of the body, or disclosure ofthe clothes of the occupant (see patent document 10.

OUTLINE OF THE INVENTION Problems to be Solved by the Invention

However, in the case of the invention disclosed in Patent document 1,too, when the elbow part is provided along the overall length of theseat part, there was a problem of the elbow part disturbing whenattempted to store the chair in the space beneath the desk.

In addition, for heat insulation, a lap cover was often provided, butwhen the lap cover was used alone, the lap cover was likely to slipdown, and the elbow rest of the chair of this kind is not long enough toreach the length from the front end to the rear end of the seat of thechair, and the drooping portion of the lap cover was likely to contactwith the floor while not in use, and the lap cover might be stained.

The present invention relates to the problems of the conventional chair,and the elbow part of the padded seat is extended nearly to the overalllength of the seat, which solves the problems of cooling of the body,disclosure of the clothes of the occupant, or necessity of considerationto pay attention to the state of the clothes, and it is a first objectthereof to present a padded seat for a chair capable of solving theproblems of the seat part disturbing the trouble of the seat part whenthe chair is stored within a space.

It is a second object of the invention to present a padded seat for achair capable of solving the problems when the lap cover is used.

Means for Solving the Problems

To achieve the first object, the padded seat for a chair of theinvention has a lifting and retaining mechanism capable of selectivelymaintaining the elbow portion tilted and raised at the inner side alongthe surface of the seat part, in the padded seat provided with elbowparts attached to both sides of the seat installed and used in thechair.

In this case, the lifting and retaining mechanism may comprise magneticattaching means disposed between a base part of the seat part and aconnecting position of the base part.

The lifting and retaining mechanism may be composed of a fastenerdisposed between the base part of the elbow part, and a connectingposition of the base part of the elbow part of the seat part.

To achieve the second object, the padded seat for a chair of theinvention has a lap cover using a sheet material capable of wrapping thelap part in a state sitting on the chair, attached integrally by way ofattaching means.

BEST MODE FOR CARRYING OUT THE INVENTION

Herein, embodiments of the padded seat for a chair of the invention arespecifically described with reference to the accompanying drawings.

FIG. 1 shows an embodiment of a padded seat for a chair of theinvention.

This padded seat 1 for a chair is used as being installed in a chair(not shown), and in this padded seat, elbow parts 12 are attached toboth sides of the seat part 11, and it is furnished with a lifting andretaining mechanism 2 for selectively maintaining the elbow parts 12between a state tilted to the inner side and an erected state, along thesurface of the seat part 11.

Accordingly, in this padded sear 1 for a chair, still more, a liftingand retaining mechanism 2 is similarly disposed between the back rest 13and the elbow part 12, so as to attach the back rest 13 to the rear endof the seat part 11.

In this case, the seat part 11, the elbow part 12, and the back rest 13are not particularly specified, but may be manufactured preferably, forexample, by using cushioning blocks of structural bodies of foamed resinmaterials of linear textile material or foamed urethane resins coveredwith enveloping materials of cotton cloth, woven cloth, blanket or otherfabrics.

The seat part 11, the elbow part 12, and the back rest 13 are may beeither connected directly by sewing enveloping materials, or connecteddetachably by way of the lifting and retaining mechanism 2, and in anycase, the elbow part 12 is tilted to the inner side along the surface ofthe seat part 11.

The lifting and retaining mechanism 2 may be composed of a magnet,magnetic attaching means of magnet and magnetic material, surfacefastener, snap fastener, and other various fasteners, or by combinationthereof.

The configuration of connecting positions of the seat part 11, the elbowpart 12, and the back rest 13 is as shown in FIG. 1, in which the baseparts of the elbow part 12 and the back rest 13 are disposed above theseat part 11, or as shown in a modified embodiment in FIG. 2, in whichthe end part of the seat part 11 is in contact with the end part of theelbow part 12, or as shown in a modified embodiment in FIG. 3, in whichthe end part of the elbow part 12 is disposed in a step part formed inthe end part of the seat part 11, and the end part of the seat part 11is disposed in contact with the end part of the back rest 13.

At the connecting positions of the seat part 11, the elbow part 12, andthe connecting positions of the back rest 13 and the elbow part 12, thelifting and retaining mechanism 2 is disposed, and therefore the elbowpart 12 can be selectively maintained between a state inclined to theinner side and an upright state along the surface of the seat part 11.

Moreover, as shown in a modified embodiment in FIG. 4, a support part 14is disposed along the connecting position of the back rest 13 and theelbow part 12, and a magnet and magnetic material (iron plate) aredisposed, for example, as the lifting and retaining mechanism 2, at theconnecting position of the support part 14 and the elbow part 12, sothat the upright state, in particular, can be firmly maintained so thatthe elbow part 12 may be selectively maintained between a state retainedto the inner side along the surface of the seat part 11 and an uprightstate.

Meanwhile, the lifting and retaining mechanism 2 may be composed ofattaching means or fastener, and an example of combination thereof isshown in FIG. 5 and FIG. 6.

More specifically, the attracting means to be disposed at both ends ofthe connecting positions of the seat part 11 and the elbow part 12 maybe composed of a magnet 21 and a magnetic element (iron plate, and thefastener to be disposed between them may be composed of a surfacefastener 23.

In this case, the surface fastener 23 is disposed between the seat part11 and the elbow part 12 by way of sheet pieces 11 a, 12 a, so that theelbow part 12 may be selectively maintained between a state tilted tothe inner side along the surface of the seat part 11, and an uprightstate.

Alternatively, the padded seat 1 for a chair may be also composed asshown in FIG. 7 to FIG. 9, that is, the lap cover 3 using a sheetmaterial so as to wrap the waist in a seated state on a chair isintegrally attached to the padded seat 1 for a chair by means ofattaching means 41.

The lap cover 3 can sufficiently insulate thermally by wrapping thewrapping the waist in a seated state on a chair, and moreover as shownin FIG. 8 and FIG. 9, if the cloth for composing the lap cover 3 islarge enough to wrap the waist sufficiently, while not in use, thedrooping portion of the lap cover 3 made of the cloth extended from theupper end of the elbow part 12 may not touch the floor, and staining ofthe lap cover 3 can be prevented, and hence it is not necessary to plaitdown the cover lap 3 carefully when leaving the chair, and handling iseasy.

Therefore, it is possible to solve problems, such as ease of slipping ofthe lap cover when the lap cover is used alone, or possibility ofstaining of the lap cover due to contact of the drooping portion of thelap cover on the floor while not in use because the length is oftenshorter than the length from the front end till the rear end of the seatpart of the chair.

In this case, the lap cover 3 is not particularly specified, but may bepreferably composed of a cloth having an appropriate heat insulationsuch as thick knit cloth, woven cloth, or blanket.

The fabric for composing the lap cover 3 is as shown in FIG. 7A and FIG.8, by using a cloth of a rectangular shape (not particularly limited,for example, about 900 mm×about 1400 to 1500 mm, same in otherexamples), It may be integrally fitted to the seat part 11 of the paddedseat 1 for a chair by way of a surface fastener as attaching means 41,or as shown in FIG. 7B and FIG. 9, by using a rectangular clothfurnished with a linear back rest cover part 31 used as covering theback rest 13, it may be integrally fitted to the seat part 11 of thepadded seat 1 for a chair by way of a surface fastener as attachingmeans 41 (in this case, further, the back rest cover part 31 and thesheet piece 32 attached to the lap cover 3 may be integrally attached byway of a surface fastener as attaching means 42), or as shown in FIG.7C, by using a rectangular cloth furnished with a back rest cover 31 tobe used as covering the back rest 13 (in this case, further, the backrest cover part 31 may be formed like a bag by way of the sheet piece 32attached to the back rest cover 31 may be integrally attached by way ofa surface fastener as attaching means 43), it may be fitted integrallyto the seat part 11 of the padded seat 1 for a chair by way of a surfacefastener as attaching means 41.

As described herein, this padded seat 1 for a chair is equipped with alifting and retaining mechanism 2 for selectively maintaining the elbowpart 12 between a state tilted to the inner side along the surface ofthe seat 11 and an upright state, and by maintaining the elbow part 12in an upright state of the elbow part 12 provided nearly along theoverall length of the seat 11, it helps to solve the problems of theconventional chair, that is, cooling of the body, disclosure of theclothes of the occupant, demanding consideration about the attention tothe state of the clothes.

In addition, by the back rest 13, heat insulation of the back side canbe enhanced.

Further, by using this padded seat 1 for a chair in particular in achair not furnished with back rest, the elbow part 12 can be maintainedin a state tilted to the inner side along the surface of the seat part11, and hence the elbow part 12 does not interfere when the chair isstored in the space beneath the desk, and the chair can be neatly storedin the space beneath the desk.
